Luminescent pro-nitroxide lanthanide complexes for the detection of reactive oxygen species

Author affiliations

Abstract

The DOTA-based ligand H3L (5) appended with a pro-nitroxide moiety has been synthesized. The europium and ytterbium complexes 5Ln show metal-centred luminescence. They react with ROS in aqueous media to give a transient iminonitroxide and a stable nitronylnitroxide radical authenticated by EPR, with change in luminescence.
